EnglishLuminescent lanthanide (Tb3+, Eu3+) complexes were prepared by reaction of Tb3+ or Eu3+ with dendritic amphiphile (3,4,5-tris(dodecyloxy)benzoate), then their liquid crystalline and luminescent behavior were studied. The complexes exhibited thermotropic liquid crystalline mesophases with columnar hexagonal structure. The complexes emitted the characteristic luminescence of the core metals. Additionally, in the Eu3+ complex, the ratio of the intensity of 614nm to the intensity of 585nm (I-614/I-585) remarkably decreased around the transition temperature from crystal to mesophase, suggesting that the coordination environment of Eu3+ gets more symmetrical due to the phase transition.
